Artificial neural networks (ANN) an alternative to MRA for calibrating mass appraisal models sale price not a suitable independent variable for a residential sales comparison model statistical software packages provide the greatest modeling features and flexibility slope function regression coefficients in excel are generated by ___ weak positive correlation correlation coefficient of 0.15 dividing a regression coefficient by its standard error how a t-value is calculated forced entry regression method available in Excel dividing residuals by the standard error of estimate how standardized residuals are calculated a scatter plot of the residuals with age good way to check whether a model has achieved uniformity for older & newer homes automatic model specification not an advantage of MRA contribution of each variable is independent of the other variables additivity assumption building residual method most common method of separating MRA values between land and buildings renovation type binary variables are most appropriate for __ thirty sales per binary variable generally needed to ensure strong confidence in regression coefficients values observed for binary variables in prior models preferred method of deriving weights assigned to scalar variables weights are not model-derived disadvantage of scalar variables does not exist logarithm of 0 difficult to explain shortcoming or limitation of polynomials effect of distance & proximity on value reciprocal transformations capture __ lot size x living area not an appropriate transformation to include in a residential model dividing the average deviation by the median coefficient of dispersion: ___ and multiply by 100 standard deviation most affected by outliers 95 percent lies within 2 standard deviations living area most appropriate for a histogram cross tabulation best for examining the relationship between 2 categorical variables quantitative variables scatter graphs show relationships between first, generate a pivot table producing a line graph in Excel examining average living area by construction year ranges line graph would be appropriate more than 1.5 box lengths below the 1st quartile or above the 3rd quartile outliers in a box plot showing distribution of sales ratios by NBHD appropriate for a box plot cost model calculations not an application of spatial analyses and thematic maps in mass appraisal x-y coordinates required for spatial analyses calibration process of determining the coefficients in a model is known as lot size independent variable in a residential model model term B5NBHD_213 hybrid model most flexible or open ended model type additive model ordinarily contains a constant handles % adjustments advantage of multiplicative models
